The high capacity electrochemical capacitors with capacitance values much higher than the other capacitors, are called as Super Capacitors. These can be categorized as a group that lies between electrolytic capacitors and rechargeable batteries. These are also called as Ultra Capacitors.

There are many advantages with these capacitors such as −

• They have high capacitance value.
• They can store and deliver charge much faster.
• They can handle more charge and discharge cycles.

These capacitors have many applications such as −

• They are used in cars, buses, trains, elevators and cranes.
• They are used in regenerative braking.
• They are used for memory backup.

The types of super capacitors are Double-layered, Pseudo and Hybrid ones.
